Reply To: Governing Equation for Energy in LES ANSYS Fluent

In ANSYS Fluent, the filter is the grid, so the equations are the same in RANS and LES. The difference lies in the calculation of mu_t.
As far as I am concerned, the value of k_t in LES is not explicitly written in the Theory Guide. However, I guess that it is k_t = mu_t*c_p/Pr_t.
